Williams places pipeline expansion in service

TULSA, Okla., Nov. 3, 2003 — A unit of Williams has placed an expansion on its Transco pipeline natural gas system into service.

The Trenton-Woodbury expansion increases firm transportation capacity by approximately 51,000 dekatherms per day to serve markets in the Northeast.

Approximately seven miles of new pipeline was installed along the company’s existing pipeline system in Burlington and Mercer counties, New Jersey.

“Transco pipeline has provided reliable, economic gas transportation services to the Northeast for more than 50 years. This expansion project will allow us to continue meeting the region’s growing energy needs and ensure the availability of clean-burning natural gas,” said Doug Whisenant, senior vice president of Williams’ natural gas pipeline business.

This is the second of three expansion projects that Williams expects to bring into service this year on its Northwest Pipeline and Transco systems.
